I have 2 WAN and 2 LAN (local and freewifi)

i'm having issue in may freewifi lan that is set to multiwan gateway and captive portal on
it is as if server 10.10.1.0 is not exisitng, cant be ping or access via freewifi lan
weird part is that freewifi clients cant received their IP via DHCP, just to access to internet.
but one I set the gateway back to "default" routing will be restored.. I can then set again to multiwan after a few minutes. and it will work again until it fails...
noticeable is usually after reboot... I will have this problem.

is something missing in my settings or this is a routing bug of sort if multiwan group is used?
it seems also if conecction changes at times from wan 1 to 2 there is sometimes a "lag" or dns error, users then must kepp refreshing the page

if more info is needed, I will try to provide

seems to be an issue with a VLAN adapter?


on a real LAN adapter setting a device to multiWAN gateway does not seem to have any issue

but on a VLAN adapater can seem to connect properly with internet without numerous retries

i'm now trying out enabling, if that would help in my issue...
hmmmm seems like there is not much people into multi wan(load balance)

firewall->settings->advance
 Disable force gateway    Disable automatic rules which force local services to use the assigned interface gateway.

EDIT: there is a slight improvement as far as experience but I still experience a "sort" of disconnected state.... I cant really pinpoint the issue becuase it does work in some point... then just disconnect... you have to keep on refreshing... please note that by using regular gateways there is no problem and the connection is fast.

without the "disable force gateway" option, disconnection is every 1minute and last for about 3osec or more
